I have a Duo-Therm AC model#59516.501 with Relay kit#3104998. installed on a 1997 Alpine light 5th wheel. I am looking for a replacement AC thats compatible without having to modify the structure. The mounting bolt spread is 13-1/4 center to center all directions. Can you recommend a model that you carry that will fit. Thanks

The Advent AC unit part # ACDOM150 will work great as a replacement for a Dometic Duo Therm unit like you have. We had a customer come back and tell us how well this worked as a replacement for a Duo Therm and that no modifications were needed so this would be what we would recommend highly.

Hey Tim welcome back! Your ARH15AACBL2 GE AC unit has the old 410a refrigerant in it so the GE Appliances item #GE64FR you were looking at isn't going to work as a replacement. The EPA mandated R32 refrigerant has been used in all new AC's…
